Description:
A spectrophotometric catalog of 238 bright stars was compared with the
Tyan Shan photometric catalog in the WBVR system. An analysis of the
photometry of ten stars in four photometric systems led to new,
corrected energy distributions in their spectra, which substantially
improved the agreement between the observed and synthetic magnitudes.
